Exhaust valve assembly of refrigerator compressor

Abstract

The invention discloses an exhaust valve assembly of a refrigerator compressor. The exhaust valve assembly comprises a valve plate, an air suction valve plate and an exhaust valve plate, wherein an air suction port and an exhaust port are formed in the valve plate, and a buffer sleeve piece is annularly connected in the air suction port; the air suction valve plate is arranged on the lower surfaceof the valve plate, and an air suction reed correspondingly matched with the air suction port is connected to the air suction valve plate; and the exhaust valve plate is arranged on the upper surfaceof the valve plate correspondingly matched with the air suction valve plate, and an exhaust reed correspondingly matched with the exhaust port is connected to the exhaust valve plate. The exhaust valve assembly is novel in structure, the contact area can be greatly reduced by changing the structures such as the buffer sleeve piece and an elastic blocking structure, the stress of the reed parts iseffectively changed, the rigid pressure of the reeds is relieved, the buffer effect can be effectively improved, and therefore further noise reduction is achieved; and through the structures such asan arc-shaped flow guide channel, the vortex energy loss caused by the surfaces of the reeds can be effectively changed, and the overall efficiency of the compressor is improved.

[0002] With the development of society, consumers have higher and higher requirements for the noise of refrigerators, and refrigeration compressors are important components of refrigerator refrigeration. The suction and discharge valves of refrigeration compressors are one of the key components in the compressor. It is to directly control the operation of the compressor in the refrigeration system. As an important part to complete the refrigeration cycle, the valve plate assembly is particularly important. Once the noise of the valve plate assembly is too large during the working process, the result will directly cause the refrigerator to malfunction. The noise is high, so it is very important to reduce the noise generated by the valve plate assembly during work. The delivery of refrigerant is carried out by the opening and closing of the suction and discharge valves of the compressor. When the existing suction valve works, its The opening process is like a cantilever beam swinging up and down. There is an inclination angle when the reed and the valve plate collide with each other. This inclination angle will cause a small leakage of the refrigerant during the refrigerant delivery process, thus affecting the cooling effect and reducing the cooling efficiency. In order to make the exhaust valve plate and the valve plate contact as flat as possible, the compressor manufacturer requires slight bending of the reed head of the valve plate, while the existing compressor suction valve plates are all made of high carbon steel or stainless steel. , the interaction between it and the compressor valve seat made of metal material has become an inevitable main noise, so the noise generated in the refrigeration compressor mainly comes from the running sound of the compressor motor, and the suction and discharge valve plates of the compressor are in the The air flow sound produced by the refrigerant under pressure during the suction and exhaust process and the collision sound generated when the compressor suction and discharge valve plate collides with the valve plate and the valve plate and the limit plate are all harmful to people.
